Dream recall, dream length, and sleep duration: state or trait factor

Longer sleep duration should be related to dream recall (longer REM sleep), but previous findings regarding the relationship between habitual sleep duration and dream recall frequency have been conflicting, whereas experimental manipulation of sleep duration yielded a significant effect. The analysis of diaries kept by the 444 participants over 14 days indicated that intra-individual fluctuations and interindividual differences in sleep duration affect dream recall.

Four meanings of “categorization”: A conceptual analysis of research on person perception

It is widely assumed that people tend to “categorize” other people. However, the term “categorization” has been used with qualitatively different underlying definitions in the person perception literature. We present a conceptual analysis in which we disentangle four existing definitions: (a) categorization as representing, (b) categorization as dichotomizing, (c) categorization as organizing, and (d) categorization as grouping. Subsequently, we show that seemingly antagonistic viewpoints in the literature may be reconciled by disentangling these definitions. Furthermore, we argue that disentangling these definitions is vital for theoretical interpretations of (past and future) empirical findings. Overall, our work aims to contribute to the clarity of person perception theories, provide novel perspectives on existing debates, and serve as a stepping stone for more differentiated models of person perception.     

Neuroticism and attachment insecurity as predictors of bereavement outcome

Adult attachment dimensions as well as the personality trait neuroticism have been shown to be related to psychological adjustment after bereavement. No investigations so far have studied the relative contribution of these constructs to grief and depression. In our study of 219 bereaved parents, the two adult attachment dimensions, attachment anxiety and attachment avoidance, were compared to the personality trait neuroticism in predicting psychological adjustment. The attachment dimensions explained a unique part over and above neuroticism, but contrary to expectations, neuroticism explained more variance than attachment dimensions. Implications are discussed.     

Knowledge of Language Transfers From Speech to Sign: Evidence From Doubling

Does knowledge of language transfer across language modalities? For example, can speakers who have had no sign language experience spontaneously project grammatical principles of English to American Sign Language (ASL) signs? To address this question, here, we explore a grammatical illusion. Using spoken language, we first show that a single word with doubling (e.g., trafraf) can elicit conflicting linguistic responses, depending on the level of linguistic analysis (phonology vs. morphology). We next show that speakers with no command of a sign language extend these same principles to novel ASL signs. Remarkably, the morphological analysis of ASL signs depends on the morphology of participants' spoken language. Speakers of Malayalam (a language with rich reduplicative morphology) prefer XX signs when doubling signals morphological plurality, whereas no such preference is seen in speakers of Mandarin (a language with no productive plural morphology). Our conclusions open up the possibility that some linguistic principles are amodal and abstract.     

Feedback in Couple and Family Therapy: A Randomized Clinical Trial

Routine Outcome Monitoring (ROM) is recommended as a psychotherapy procedure to serve as clinical feedback in order to improve client treatment outcomes. ROM can work as a warning signal to the therapist if the client shows signs of no change or deterioration. This study has investigated whether any difference in outcome could be detected between those clients in couple and family therapy who used the Systemic Therapy Inventory of Change (STIC) feedback system (ROM condition) versus those who were offered treatment without the use of STIC (“treatment as usual” or TAU condition). A sample of 328 adults seeking couple and family therapy in Norway was randomly assigned to ROM versus TAU conditions. Outcome measures were The Outcome Questionnaire–45 and The Revised Dyadic Adjustment Scale. The results demonstrated no significant differences in outcomes between the ROM and TAU. Possible explanations of this result related to design and implementation issues are discussed.     

“Playing by the Book”: Determinants of Children's Preference for Replicating and Originating Play

Play is children's most important daily behavior and when children play, they do so in multiple ways. With two studies, this paper explores how children perceive a continuum of two play types, namely replicating play (in which models, guidelines, and examples are used to reach an intended result) and originating play (in which children create something from the mind, think freely about how they will play, are less restricted by given models, etc.). Study 1 (N = 56, M_age = 9) quantitatively shows that both play types occur and tests if children also describe the play types as we define them. Results show that children who play originating (vs. replicating) believe they follow less (vs. more) rules and do their own thing more (vs. less), which verifies the definitions of both types of play. Study 2 includes 16 in-depth semi-structured interviews (M_age = 10) and shows which determinants children identify as triggers for engaging in play that has more replicating or more originating elements.
